Rather old document from 2010: Cisco + IPv6 over CAPWAP protocol:
http://d2zmdbbm9feqrf.cloudfront.net/2012/usa/pdf/BRKEWN-2010.pdf
Access point support from many vendors seems okay. But another vendor gap
on IPv6 is WiFi AAA, policy servers, and tunnel servers from vendors like
Ericsson and ALU. I hope to see richer IPv6 support for these aspects of
WiFi (helpful for those operating lots of outdoor WiFi systems for
example).

It will prevent *all* multicast traffic from using bandwidth towards
hosts not in the multi

The switch then knows what listeners are where, so when for example an

Okay, so then to answer my o

For example, multicast is used by ND, the IPv6 equivalent of ARP. MLD
snooping means only a few hosts (typically only one, in fact) in the

MLD snooping allows the switch to send multicast traffic only to those

MLD Snooping only seems important to me if you are actually going to do
multicast outside of the local broadcast domain, which I can't imagine
doing in most service provider environments. Am I missing a reason f
MLD Snooping and IPv6 ACLs are a must. Check to make sure that the solution
allows for many (for your network's definition of many) IPv6 addresses per
host. You'll have at least three per host between link local, global, and
one or more privacy addresses.
